"And he gave many honours to those who had worshipped him. And he exalted them over those who had opposed him and withstood him. And he spread out the land on the right side into many lands. And he made them each into ranks, and each into aeons, and each into worlds, and each into heavens, and each into firmaments, and each into places, and each into spaces. And he appointed laws for them. He gave to them commandments: "Abide in my word and I will give to you eternal life '. And I will send you powers. And I will strengthen you with spirits of power, and I will give you authority as you will.
And no one will prevent you in what you wish. And you will beget for yourselves aeons and worlds and heavens, (so that) the intelligible spirits come and dwell in them. And you will become gods, and you will know that you are from God, and you will see him, that he is God within you, And he will dwell in your aeon." And the Lord of the All said these words to them. And he withdrew from them and concealed himself from them '." [The Untitled Gnostic Text] (Bruce Codex)
Oh, I would say so.
Also, the Signs & Tokens & Passwords used in the Mormon Temple are found within Ancient Jewish & Early Christian Writings...
Mormon Temple Rituals and the Mormon Temple Endowment are based upon Ancient Jewish and Early Christian ordinances and rites and ceremonies. Washings, Anointings, Blessings, and Sealings are all a part of the Old & New Testaments.
Ancient Jews and Early Christians taught Hand Signs of Recognition, Ritual Handclasps, and Passwords in order to pass by the Angels standing as Sentinels at the Gates of each of the Progressive Levels of Heaven.
Early Jewish/Early Christian Sources: (Containing Brief Excerpted Quotations from the FAIR LDS Article "Early Christian & Jewish Rituals Related to Temple Practices")
The 1st & 2nd Books of Jeu/Ieou and The Pistis Sophia describe how Jesus instructed the apostles regarding the seals, names, and ciphers (hand-signs) they must use in order to prompt the "watchers" or guardians of the various heavens to open the veils and allow them entry.
In the Gospel of Philip it is said, "The Lord revealed unto me what the soul must say as it goeth up into heaven, and how it must answer each of the powers above." The initiates in [the Acts of John] have entered into the godhead, fused with it. The voice of the mystery god imparts unto them the symbols, the marks of recognition and passwords . . .
In the Apocalypse of Paul, we find the apostle encountering angels at the gate of each of the ten heavens, who open to him because he was accompanied by the Holy Spirit. When he arrived at the seventh heaven, he encountered an old man who interrogated him. The Spirit instructed the apostle, "Give him the sign that you have, and he will open for you.' And then I gave him the sign . . . and then the seventh heaven opened."
A similar story is found in the account of the vision attributed to the prophet Isaiah. We learn that Jesus had to give passwords to angels while descending through the seven heavens to be born on earth.
Jewish lore has similar beliefs. In Hekalot Rabbati, the adept passes through the seven doors of the seven heavenly temples, past angels whose name he must give, while presenting a seal, in order to enter the presence of God. The names and seals given to the angels are also mentioned in 3 Enoch.
Even the Bible notes (Revelation 21:12- 13) that twelve angels guard the twelve gates of the Heavenly Jerusalem.
The role of the heavenly sentinels, often called "thrones" because they are sometimes described as sitting on thrones, is noted in the Apocalypse of Elijah:
"The Lord said, 'I will write my name upon their forehead and I will seal their right hand, and they will not hunger or thirst. Neither will the son of lawlessness prevail over them, nor will the thrones hinder them, but they will walk with the angels up to my city.' Now, as for the sinners, they will be shamed and they will not pass by the thrones, but the thrones of death will seize them and rule over them because the angels will not agree with them." (Apocalypse of Elijah 1:7-11)
These ascension narratives often included ritual handclasps, such as were included in the Christian Gnostic, Jewish Gnostic, and Greek mysteries. Whoever was being conducted through the heavens was lifted along after grasping the right hand of the guiding angel or God.
For example, in the Gospel of Nicodemus, Jesus descends into Hades after His death, grasps the right hand of Adam, and leads him to paradise with all the saints following:
"And the Lord . . . took the right hand of Adam and went up out of hell, and all the saints followed him. . . . He went therefore into paradise holding our forefather by the hand, and delivered him, and all the righteous, unto Michael the archangel."
A similar occurrence was also described in 1 Enoch:
"And the angel Michael, . . . seizing me by my right hand and lifting me up, led me out into all the secrets of mercy; and he showed me all the secrets of righteousness."
The clasping of hands while revealing secrets is known from a number of early documents. In the Second Apocalypse of James, Jesus tells the apostle that he would reveal things to him, then told him "stretch out your [hand]. Now, take hold of me."
In connection with the ritual enactment of the heavenly ascent, it is also interesting to note that certain Gnostic ascension narratives also contained ritual handclasps. For example, in one Manichean narrative, the Primeval Man is drawn up to heaven by celestial messengers:
"The Living Spirit, who was accompanied by the Mother of Life, extended his right hand to Primeval Man. The latter seized it and thus was drawn up out of the depths of the world of darkness. Together with the Mother of Life and the Living Spirit he rose up and up, soared like victorious light out of darkness, till he was returned to the paradise of light, his celestial home, where his kin awaited him."
"The right hand of fellowship" [dexias koinoas didonai tini] is given "as a sign of friendship and trust." (Galatians 2:9)
"Him that overcometh will I make a pillar in the temple of my God, and he shall go no more out: and I will write upon him the name of my God, and the name of the city of my God, which is new Jerusalem, which cometh down out of heaven from my God: and I will write upon him my new name." (Revelation 3:12)
"He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh will I give to eat of the hidden manna, and will give him a white stone, and in the stone a new name written, which no man knoweth saving he that receiveth [it]." (Revelation 2:17)
